Abstract:
The minimum energy requirements for buildings have continued to increase in recent years. Energy calculations are used to check whether the building meets the requirements of the Building Energy Act. However, the energy calculations do not always represent the actual energy consumption of the building. Within the scope of the diploma thesis, a validation of energy calculations in residential buildings was to be carried out. In a first step, the calculation methods and procedures for determining the energy consumption of buildings were to be shown and compared. In particular, possible advantages and disadvantages were to be considered with regard to the representation of the later "reality". On the basis of a selection of existing buildings, the necessary data was to be collected, compared with regard to the calculation methods and types of systems, and subjected to an initial qualitative evaluation. Based on the determined data, a target/actual comparison with calculation methods, deviation analyses and research into the main causes for the deviation had to be set up. The results of the first qualitative assessment were validated. On another object, suggestions for improvement for an optimal procedure and an application guideline for the building cooperative/the building owner or the expert user were to be developed. The interaction of different plant systems was to be considered and an outlook was to be given on the best possible combination with regard to the best use of renewable energies and the covering of peak loads. This was also to be done in consideration of the further increase in energy prices or temporary shutdown scenarios of the energy supply (black outs).
